Modern Fiber Optic Submarine Cable Telecommunication Systems Planning for Explosive Bandwidth Needs at Different Deployment Depths

摘要

The explosive bandwidth needs, especially in the inter data center market, have pushed transmission data rates to100 Gbit/sec and beyond. Current terrestrial fibers are inadequate for long haul, high bandwidth deployments. Tosolve these problems a new fiber is introduced for terrestrial high bandwidth deployments: different polymericcore fibers with enlarged effective area with a significant optical signal to noise ratio improvement over otherconventional terrestrial single mode fibers. To ensure the new fiber may be deployed robustly a new coatingstructure was employed. A rigorous cable structure was then chosen for evaluation. Based on experimental data,both the deep ocean water temperature and pressure are tailored as functions of the water depth. As well as theproduct of the transmitted bit rate and the repeater spacing is processed over wide ranges of the affectingparameters. It is taken into account the estimation of the total cost of the submarine fiber cable system fortransmission technique under considerations. The system capacity as well as the spectral losses, and the dispersioneffects are parametrically investigated over wide range ranges of the set of affecting parameters {wavelength,ocean depth (and consequently the ocean pressure and temperature), and the chemical structure}.
